Titan: Data Loading and Transactional Benchmark

The Aurelius team describing an advanced benchmark of Titan, a massive scale property graph allowing real-time traversals and updates, sponsored by Pearson, developed and run over 5 months:

The 10 terabyte, 121 billion edge graph was loaded into the cluster in 1.48 days at a rate of approximately 1.2 million edges a second with 0 failed transactions. These numbers were possible due to new developments in Titan 0.3.0 whereby graph partitioning is achieved using a domain-basedbyte order partitioner.

✚ The answer to why Titan is built on Cassandra can be found in this interview between Aurelius CTO Matthias Broecheler and DataStax co-founder Matt Pfeil:

[…] we don’t have to worry about things like replication, backup, and snap shots because all of that stuff is handled by Cassandra. We really just focus on: “How do you distribute a graph?”, “How do you represent a graph efficiently in a big table model?”, “How do you do things like etched compression and other things that are very graph specific in order to make the database fast? And, lastly, “How do to build intelligence index structures so that the graphs traversals, which are the core of any graph database, so that those are as fast as possible?”
